“It shall not seem hard unto thee, when thou sendest him away free from thee; for he hath been worth a double hired servant to thee, in serving thee six years: and the LORD thy God shall bless thee in all that thou doest.”
King James Version (KJV)
15:17 For ever - All the time of his life, or, at least, 'till the year of jubilee. Likewise - That is, either dismiss her with plenty, or engage her to perpetual servitude, in the same manner and by the same rites.
15:19 All the firstling males thou shalt sanctify - Giving them to God on the eighth day. And thou shalt do no work with the female firstlings of the cow, nor shear those of the sheep. Even these must be offered to God as peace - offerings, or used in a religious feast.
15:20 Year by year - Namely, in the solemn feasts which returned upon them every year.
